Rotary Vacuum Paddle Dryer

The Rotary Vacuum Paddle Dryer is a high efficiency dryer, specially designed for products with high viscosity during drying phase, with high torque requirements.

The principle of the Paddle vacuum dryer is its operation through a body, shaft and blades which is fully heated to maximize heat exchange with its blades rotating very close to the wall at low speed for a continuous renewal of the product in direct exchange with the wall.
